| Outline of Final Research Achievements |
The purpose of this study was to construct new coupled electronic properties related to magnetism with low energy loss in magnetic insulators. In particular, we focused on magnetoelectric phenomena such as electric-field control of magnetism. The followings are examples of the achievements: (1) non-volatile electric-field control of magnetism at room temperature in magnetoelectric hexaferrites, (2) construction of a new glass state called “toroidal glass” and its demonstration through magnetoelectric effect, (3) construction of enantiomerism for electric quadrupole order, and (4) enhancement of magnetically-induced electric polarization by applying high pressure.
